Image Comparison Slider
Compare two images by dragging a divider. Zoom in to inspect differences in compression, color, retouching or design.
Compare the same photo before and after editing
Add the original first and the edited file second. Drag the divider across a face, a text edge or a flat background, then zoom to inspect the detail. For a fair comparison, start with two files that have the same dimensions and crop.
When to use the slider or a collage
The slider is an interactive preview on this page. To share one downloadable image, use the side-by-side template in the photo collage maker. To compare compression settings, make another copy with the image compressor.
Frequently Asked Questions
Does the slider export an image or embed code?
The slider is for comparing files in the browser. Use the collage maker if you need a shareable side-by-side image.
Why should both images have the same crop?
The comparison overlays both files. A change in crop or subject position can make it hard to tell whether an apparent difference came from the edit or from misalignment.
